Surface Book vs. Surface Book 2 (13 inch): Tech spec showdown

The Surface Book 2 has finally been unveiled, after months of speculation and secrecy, but how good is it? And how does it stack up to the original Surface Book?

Speaking of which, the Surface Book 2 comes in two flavors this time around: a 13.5-inch version and a 15-inch model with more powerful specs.

Here's a look at how much of a bump you'll get with the new 13-inch model versus the original Surface Book, which launched in 2015.
